Adulticiding is the use of pesticide to control adult mosquitoes. This can be accomplished two ways, either by truck
mounted equipment or by aircraft. When a need is determined through our surveillance program, ground spray trucks will run Monday through Thursday evenings between 8pm-2am. The pesticide used is Duet delivered
as an aerosol at 4 ounces per acre. These trucks do not leave the road unless prior arrangements have been made.
If you wish to exclude your property from ground spraying, please complete a Spray Avoidance Request form, found on the website, and return it to the Mosquito Control Division.
During the spray season, May through October, spray information will be posted on our website and on the mosquito spray hotline
by 3pm each day. The Mosquito Control hotline is 757-890-3793.
